Standard housing design

SBD plummer (pillow) block housings and THD take-up housings are non-split housings. They consist of a housing body and two covers. The covers are bolted to the body with six or eight bolts. SBD and THD housings are supplied with different covers depending on the shaft-bearing combination (→ Typical shaft-bearing combinations).

SBD housings are available in two designs , depending on the housing size. The main difference is the holes for the attachment bolts: one design has cast oblong holes (fig. 1), the other has drilled holes (fig. 2). Other design differences include the overall shape of the housing and the thickness of the reinforcement ribs.
